Why varicose veins ache more at night

What you are feeling is common

Many people with varicose veins notice a familiar pattern: the leg feels heavier, achier, or more swollen as the day goes on. That does not mean you are imagining it. It usually reflects how pressure builds in leg veins when you have been upright for hours and the valves are not doing their job properly.

Why symptoms often worsen later in the day

Healthy leg veins rely on one-way valves and the calf muscle pump to push blood back up toward the heart. If valves are leaky (venous reflux), blood can fall backwards and pool in surface veins. The longer you are upright, the more that pooling and pressure can build.

Common reasons the evening feels worse

• Gravity: standing and sitting with feet down increases pressure in leg veins.
• Pooling: reflux allows blood to drift back down into surface veins.
• Swelling: fluid can leak into surrounding tissue, making the ankle and calf feel tight.
• Inflammation: irritated vein walls can cause aching, throbbing, itching, or a restless sensation.
• Heat: warm weather, hot baths, and heated rooms can dilate veins and make symptoms more noticeable.

What helps (and why it helps)

Small, practical changes often make a real difference. The aim is to reduce venous pressure, keep blood moving, and limit swelling.

Try these steps in order

1. 1
   Walk for 5–10 minutes every hour or two if you can

   Movement activates the calf pump.

2. 2
   When sitting, raise your feet on a stool so your ankles are not below your knees

3. 3
   If you stand for work, shift weight, do gentle calf raises, and take short walking breaks

4. 4
   Use cool water on the legs at the end of the day if heat makes symptoms worse

5. 5
   Consider compression stockings if symptoms are frequent

   They reduce swelling and can ease aching by supporting the veins.

When to consider a duplex ultrasound scan

If symptoms are persistent, getting a duplex ultrasound scan can be very helpful. It shows whether there is reflux in a main trunk vein (such as the great saphenous vein) and which veins are actually responsible for the pressure and bulging you can see.

A scan can clarify whether you are likely to benefit from treatment

• Aching/heaviness that builds through the day and improves with elevation can fit venous reflux.
• Visible varicose veins are not always the whole story; the source may be higher up.
• Treating the correct refluxing vein is the biggest factor in getting a durable improvement.

What not to ignore

Most varicose vein symptoms are not dangerous, but some signs should prompt urgent medical advice.

When self-help is not enough

If you are regularly planning your day around leg discomfort, or if swelling is becoming a daily problem, it is reasonable to consider treatment. Modern options such as radiofrequency ablation, foam sclerotherapy, and avulsions are usually walk-in, walk-out procedures under local anaesthetic.
